How to make particles of an object that is made of several arrayed objects?
So I had a quick player around with a scene I just made.

You have to make sure that the object (in my case plane) is in a sperate collection to the the lupin objects.

In the &quot;Particle Properties&quot; tab in the outliner toggle &quot;Advanced&quot; in Hair to get the some more options you might need.

Under the &quot;Render&quot; tab, switch &quot;Render As&quot; to Collection (which I believe you did). In the same options toggle &quot;Whole Collection&quot; in order for it to emit the whole lupin/object as one and not random segments.

In my case (you may not have to) Under the &quot;Rotation&quot; settings I had to change the &quot;Orientation Axis&quot; to Global Y, but have a play around with it, it may be different in your case.


Note You should play around with the &quot;Hair Length&quot; under emission tab in conjuncture with the &quot;Scale&quot; under the &quot;Render&quot; tab in particle properties to get the size you want.
